CHARLES J. MATTISON, OF OSWVEGO, NEV YORK.

MACHINE FOR PACKING GRANULATED 0R POWDERED SUBSTANCES.

SPECIFICATION forming part of Letters Patent No. 571,492, dated November17, 1896. Application filed. January 7,1896. Serial No. 574,599. (Nomodel.)

.To aZZ whom it may concern.-

Be it known that I, CHARLES J. MATTISON, of Oswego, in the county ofOswego and State of New York, have invented new and useful Improvementsin Machines for Packing Comminuted Material Around a Solid Core, ofwhich the following is a specification.

Thisinvention relates to improvements on the machine for packingpulverulent substances for which Letters Patent No. 383,136 were grantedto me on the 22d day of May, 1888; and the object of my presentinvention is to mechanically effect the packing of gram ulated orpowdered material around a solid core in a suitable shell or casing,said core being made to either form a permanent fixture in the package,or, when preferred, it may form part of the containing-shell for thepackage and be removable from the package when said shell is removedtherefrom.

In the accompanying drawings, which are herein referred to and form partof this specification, Figure 1 is a vertical section of part of apacking-tube for my machine, a shell open at top and bottom forcontaining the packed material, and a block on which said shelltemporarily rests in the operation of packing, the packing-auger beingshown in side elevation and the several parts arranged as preparatory tothe packing of the material in the containing-shell; Fig. 2, a verticalsection of said packing-tube, shell, block, and the packingauger, withthe solid core shown in side elevation and the several parts arranged asafter the packing of said shell has been completed; Fig. 3, an invertedplan view of my improved packing-auger detached from thepacking-machine; Fig. 4., a vertical section of a filled shell, with thesolid core shown in side elevation; Fig. 5, a side elevation of thelower part of my improved packing-auger in a modified form, with thelower portion of the tubular center broken away; and Fig. 6, a frontelevation of a packing-machine adapted to effect my method of packingcomminuted material around a solid core.

As illustrated in the drawings, N designates the framework of apacking-machine that is essentially like the one above referred toherein, said framework including a table or platform 1 for holdingunfilled shells for packages and for other purposes; M, a yieldingplatform that is secured in a horizontal position to the upper end of aslide 2, which moves vertically in guides 8, secured to the framework.The down ward movement of said yielding platform is resisted by acounterweight (not shown in the drawings) for the purpose of obtaining arequired density of the packed material.

0 is a hopper for containing a supply of the com minuted materialpreparatory to packing the same into shells or cases. Said hopper issecured to the framework N in such manner that its lower end will bedirectly over the yielding platform M.

A is a packing-tube that is reinovably attached to .the lower end of thehopper 0, so that the center line of said tube will range in line withthe center line of the hopper. The upper end of said packing-tube ismade to fit the lower end of said hopper, and the interior of the lowerportion of said packing-tube should be cylindrical and of a diametercorresponding to the diameter of a packing-auger which rotates therein.The outer form of the lower portion of said packing-tube should conformin shape and size to the shell or case it is designed to fill.

B is a packing-auger that is fitted to revolve in the packing-tube A toeffect the packing of granulated or powdered material around the sidesof a solid core G when loosely inserted in a tubular center D of saidpacking-auger. Around said tubular center an interrupted screw-thread isgenerally formed by means of inclined segmental sections 0, which aresecured to said tubular center; but, when preferred, a continuousscrew-thread maybe secured to the outer side of said tubular center toform the packing-auger, and in either form of said packing-auger thelower end of its tubular center should remain open, but its upper endmay be closed, either by a closure that forms an integral part of saidtubular center or by attaching the packing-auger to the lower end ofapacker shaft P. Usually the solid core G is fed downward by a spring E,that is contained in the bore of the tubular center D and will feed thesolid core G down ward in a positive manner, or if the solid core isproperly made it can be fed downward by its gravity; but in either casethe feeding movement of the solid core should correspond to thecompression of the mate rial into the shell provided for the finishedpackage.

P is a packer-shaft arranged vertically in the center of the hopper O.To the lower end of said packer-shaft the packing-auger B is removablyattached, so as to substitute packing-angers of different sizes andsuited to different grades of material. The upper end of saidpacker-shaft is provided with a bevelgear R, that meshes into a likegear secured to a horizontal driving-shaft Q, which is pro vided with afriction-pulley S, that derives motion by a belt from any proper motor.The. pulley S. is arranged to revolve loosely on the. shaft Q, and the.latter is provide v with a spline 4, on which a friction-clutch 5 isfitted to slide. Said clutch. is adapted to engage in frictional contactwith the pulley S and connect/the shaft Q to said pulley. An operating-lever T is fulerumed to. a

bracket 6 on the framework N, and an arm E 7 on said lever is fitted tomove said clutch to effect a connection or disconnection of said pulleywith the driving-shaft Q according to the requirements then existing. Bydisconnecting said clutch from the pulley S a stoppage of the motion ofthe packing-auger B will be effected.

Uis. a releasing-lever that is fulcrumed to a bracket 8 on the frameworkN. Said releasing-lever is connected to the operatinglever Tby a rod V,so. that by raising the yielding platform M to. the extremity of itsupward movement a lug 9 011 the slide 2 will take against the free endof said operatinglever and swing the latter into a position (shown byfull lines in Fig. whereby the l frictionsclutch 5 will be engaged withthe pulley S to. impart motion to. the drivingsh-aft Q. Theoperating-lever T is retained in its raised position by a locking-lever(not shown in the drawings) until the releasinglever U is moved by a cam10 on the slide 2 to disengage. said rel'easing-lever'from thelocking-lever and allow the releasin g-lever U to.- tilt downward into aposition (indicated by dotted lines in Fig. 6). that will effect adisengagement. of the friction-clutch 5 from the pulley S, and therebythe motion of the packing-auger B will be stopped automatieal'ly.

H is a shell or case for containing the comminuted' material and thesolid core after the packing has been accomplished. Said shell may bemade of any suitable material in any preferred form-either tubular,polygonal, rectangular-and with either one or both of its: ends openuntil the operation of packing has been completed, but if either of itsends must be closed it should be the lower one, so as to allow the openend to be slid onto the packing-tubeA, and in such construction thesolid core G can be centrally attached tothe bottom of the shell I-I, soas to effect an insertion of said core into the tubular center Dsimultaneously with the placing of the shell 11 on the exterior of thepacking-tube A.

I is a block which is designed to form a temporary bottom for the shellI-I during the operation of packing the comminuted material into. thelatter if said shell is made with an open lower end. When a recess is tobe formed in the lower end of a package during the operation of packingthe eomminuted material therein, the upper portion of said block shouldbe formed to shut into the lower end of the shell H to a distance thatwill equal the depth of the recess to be formed thereby, [and theupperface of said block should have a recess J formed centrally therein toreceive the lower end of the core G and position the latter in the shellH. lVhen a recess is to be fdi med at the upper end of a package, thepackingwauger B should cease its rotations when the lower end of saidauger has reached 1 a point where the bottom of the recess is to 1 belocated. K designates a filling of comminu-ted ma- ;terial which, asshown in Figs. 2 and 4, is packed into a shell H between the wall of theglatter and the periphery of a solid core G, l which is usually locatedcentrally in said shell.

\Vhen my invention is applied to producing porous cups for electricalbatteries, the filling K consists of comminuted carbon or materialsuited to that purpose, and under the same conditions the solid core Gshould be a solid bar of carbon or an equivalent material, and said coreshould be provided with a screw L for securing a binding-post of an oldand well-known construction to said core for the purpose of connectingthereto electrical conducting-wire in the usual manner.

The modified form of my packing-auger (shown in Fig. 5) only differsfrom the packing-auger B, hereinbefore described, by having the lowerend of its tubular center D extended downward below the lower end: ofthe screw=threads of the packing-auger 13, and the object of thismodification is to facilitate the inserting of a central corein thetubular center of a packing-auger while the latter is retained inthepacking-tubeof the machine.

The filled shell H (shown in Fig. 4) is designed for use as a porous cupfor electrical batteries, and the recesses formed in the upper and lowerends are filled by pouring in melted wax or paraffin.

The arrangement of my invention as shown in the drawings and describedherein is designed for filling porous cups for electrical batteries,whether the central core is a permanent part of the cell oris removabletherefrom.

My invention is applicable, without further improvement, to the purposeof making nonconducting jackets for steam-pipes or other pipes needingsuch protection, which jackets are usually madeof granulated cork. Forthat purpose a metallic shell is provided with a closed lower end havinga solid core formed on or secured to said bottom. The diameter of thebore of said shell is made to suit the diameter of the jacket required,and the diameter of the solid core corresponds to the bore of saidjacket, the height of the shell corresponding to or nearly to the lengthof the tubular section of the jacket, the packing-auger being formed tosuit the bore of the shell and the diameter of the solid core. Thegranulated cork is packed by a packingmachine into said shell, and thelatter, with its filling, is then placed in a furnace and heated untilthe cork is transformed into a solid consistent mass, after which theshell is taken off and the core removed, leaving a tubular cork jacket.While I have described my invention as applied to two special purposes,it is applicable to many others where granulated or powdered material isto be packed around a solid core of any size or form.

Being aware that it is old and well known to provide a packing-machinewith a movable platform for holding a barrel or other receptacle duringthe operation of packing granulated or powdered material thereinto, saidplatform being arranged to yield under a pressure that exceeds the meansemployed for resisting such yielding movement, I do not claim per 56that feature in packing-machines, the same being fully shown anddescribed in Letters Patent N 0. 19,572, that were granted to JudsonMattison on the 9th day of March, 1858; but

What I claim as my invention, and desire to secure by Letters Patent,is-

1. I11 an apparatus for compressing comminuted material into a shell orcase around a solid core, the combination, with a revolublepacking-auger provided with a tubular center adapted to temporarily holda solid core during the operation of compressing the comminutedmaterial, of a yielding platform arranged to hold said shell or case andto move downward in opposition to a movable resistance, as hereinspecified.

2. In an apparatus for compressing comminuted material into a case orshell around a solid core, the combination, with a revolublepacking-auger provided with a tubular center that is adapted totemporarily hold a solid core during the operation of packing thecomminuted material; said packing-auger being constantly surrounded by apacking-tube, and a spring contained in said tubular center and arrangedto feed down the solid core correspondingly to the filling of saidshell, of a yielding platform arranged to hold said shell or case and tomove downward against the opposition of a movable resistance, as hereinspecified.

3. In an apparatus for compressing comminuted material into a shell orcase around a solid core, the combination, witha revoluble packing-augerprovided with a tubular center that is adapted to temporarily hold asolid core during the operation of compressing the comminuted material,of a yielding platform arranged to move downward against the oppositionof a movable resistance,*and a block placed or fixed on said yieldingplatform and provided witha recess for retaining the lower endofsaidcore duringthe operation of compressing the comminutedmaterial in thecase or shell; said block being adapted to form a recess in the lowerend of a package of said material, as herein specified.
